🚨 New preprint out!
“Fluorescence lifetime estimation: a practical approach using Flipper-TR FLIM” with Tithi Mandal and @rouxlab.bsky.social
We benchmark and describe step-by-step Flipper-TR FLIM measurements across different set-ups and and strategies.

Fluorescence lifetime estimation: a practical approach using Flipper-TR FLIM
Flipper-TR is a membrane dye sensitive to lipid packing widely used to probe membrane tension in live cells via fluorescence lifetime imaging microscopy (FLIM). However, no consensus currently exists ...

I am pleased to 📣 today’s superb thesis defense by Christian Schroer on “Chemical strategies for studying lipid signaling and transport”. Part of his work was recently published in the JLR; the other part will follow soon. A very proud and somewhat tipsy “Doktorvater” 🥂

The @embo.org ESCRT meeting was packed with membrane remodeling from every branch of the tree of life🌳. Some awesome science 🧪 highlights in the next posts 🧵. But a first impression… the venue!! Wow, Caux castle up a cogwheel train, overlooking Lac Léman! Perfect! 🌄 Thank you @rouxlab.bsky.social 🤗

🤩 Last week I successfully defended my PhD!
It was such a special day, made even better by having friends, family, and colleagues there with me. Thanks for all the support and kind words!
Huge thanks to my jury members for the thoughtful feedback and conversations.

This was a truly exciting talk from Aurelien Roux @rouxlab.bsky.social from Univ. Geneva 👏👏. From his landmark work on membranes to tissues now, the continuing theme is the role of geometry, topology and curvature in morphogenesis. Thanks for visiting us 🤩

The amazing tour de force of the great @lcferme.bsky.social is now out in its final form in @ScienceAdvances (not on Bluesky???). It was hard work and all the conceptual advance was her doing. Check it out: www.science.org/doi/epdf/10....
